Please add CurrencyStrengthSlope or other indicators you want to your post.
Krelian, nice dax thread for me as I'm also german, clean system, but when you just have moving averages, you will loose on poor trends or sideways.

What do you suggest to filter these times?

I would add a vola-based band as minimum sl-line, which goes with the trend instead of growing in both directions like bollinger bands.
I prefer ema 63, it is 3x 21, a fibonacci number, which occurs everywhere in nature.
Mladen made also some indicators with atr-bands like averages.

What are your favourite indicators?
